On: A third world engineer responds to “RISC-V: They should have known better”

Well, there is some speculation regarding these chips so no sense arguing too much about it.

That said, the SpacemiT K3 is already faster than a Pi 4 and even substantially faster than a Pi 5 for multi-core and vector stuff. And that is before counting the other 8 “AI cores” it has.

These chips will be quite a bit faster than a K3, so certainly much faster than a Pi 4.

Neat! Hopefully these new architectures can beat the Pi5, though even that's still far away from Zen 1 let alone Zen 3.

I'll push back a little on this. It can be faster under certain workloads, but is not universally. It's behind in geekbench https://browser.geekbench.com/v7/cpu/compare/146501?baseline..., and in compilation workloads: https://www.phoronix.com/review/spacemit-k3-pico-itx/3
